I'm trying to setup a GitHub repository for a project that will involve the use of an API Key. In order to keep that key a secret, I have decided to make a .xcconfig file with the API Key and add the .xcconfig file to my .gitignore. So far I have linked the file with my build settings for the app target. But I'm not actually sure how to go about calling the variable in my swift code. I know that there are environment variables within the Xcode build schemes, but I'm not sure how you would call them from there either. Is there some kind of framework that I need to call? Nothing online seems to be pointing to linking to the actual file itself.

im wanting to make apps for my Mac. I’m not interested in making a profit or uploading to the App Store at the moment and I’m just looking for a hobby. I’ve been learning swift through the “learn to code” games in swift playgrounds, and I feel like I’m ready to take on Xcode and app making. So far I have been experimenting with SwiftUI and a few other external libraries. But I still don’t feel like my skills are best developed yet. Which platform should I use to further advance my skills? I want to try continuing with macOS, but I feel like there aren’t enough resources and tutorials available for it. And I know that there are boatloads of resources for iOS, but I currently can’t afford to enroll in the apple developer program, which leaves me locked out and restricted in how much I can do.

I'm trying to work with the predicate editor because it's a major part of an app I'm trying to make, but for some reason. It keeps appearing wrong It looks like this after I build it: This is how it appears in the Interface Builder: Was there a step that I missed? Is there some sort of code that needs to be added first? I'm fairly new with swift but I have been playing around with the interface builder for a little while so I sort of understand it.
